For networks that need addresses

Lease IPv4 space
without buying it.

Verified blocks from owners whose registry records we have checked. Authorisation, routing objects and blacklist monitoring are part of every lease — not extras you chase afterwards.

Buying IPv4 is slow, expensive and hard to undo.

No capital outlay

A /24 on the transfer market runs to tens of thousands of dollars before broker fees. A lease turns that into a predictable monthly line item you can stop when the requirement ends.

No transfer paperwork

Registry transfers mean justification documents, officer attestations and a queue at the RIR. A lease leaves the registration where it is, so there is nothing to file and nothing to wait for.

Reversible

Requirements change. Hand a leased block back at the end of the term instead of carrying an asset you no longer need and having to find a buyer for it.

Five steps from browsing to announcing.

Create an account and get verified

Tell us who you are and what you intend to use the space for. Verification protects the owners whose addresses you will be announcing, and it is what lets us show you full block details rather than masked ones.

Find a block that fits

Filter the marketplace by size, RIR, price per address, minimum term and routing status. Every listing shows its current blacklist standing and whether delivery is instant or within 48 hours.

Agree the terms

Choose your term length and review the lease agreement. The monthly rate, minimum term and permitted use are all fixed at this point — there are no setup fees added later.

Receive your authorisation

Your LOA is generated and signed automatically. Where the owner has connected their registry API, the ROA and IRR route object are created at the same time so your announcement validates immediately.

Announce and monitor

Send the LOA to your upstream and announce the space. RepRadar keeps checking the block against 20 blocklists for as long as you hold it, and emails you if anything changes.

Every lease, not just the expensive ones.

Signed LOA

Generated on activation, downloadable from your dashboard for as long as the lease runs.

ROA & RPKI

Created for your ASN where the owner's registry supports it, so your route validates.

IRR route object

Published so upstreams building filters from IRR data accept your announcement.

Blacklist monitoring

Continuous checks against 25 live blocklists, with email alerts on any new listing.

Before you commit.

How quickly can I get addresses?

For ARIN, RIPE and APNIC blocks where the owner has connected their registry API, authorisation and registry objects are created as soon as your lease starts — usually within minutes. LACNIC and AFRINIC, and any owner who has chosen manual provisioning, are handled by our team within 48 hours.

Do I get a Letter of Authorization?

Yes. An LOA is generated automatically the moment your lease activates, signed by the registered owner of the block, and available from your dashboard. Upstream carriers ask for this before they will route the space for you.

Can I announce the space with my own ASN?

Yes. Every lease includes route authorisation. Where the owner supports it we also create the ROA so your announcement passes RPKI validation, and an IRR route object so filters built from IRR data accept it.

What is the minimum term?

Most owners set a three-month minimum; some accept monthly. The minimum term is shown on every listing before you commit, and you can filter the marketplace by it.

How do I know the addresses are clean?

Every block is checked against 25 live DNS blocklists before it is published, and monitored continuously afterwards. The marketplace shows the current clean/listed count for each block, and RepRadar emails you if a monitored address is newly listed during your lease.

What happens at the end of the term?

Leases roll month to month unless you or the owner give notice. If you stop paying, there is a ten-day grace period with reminders before the route authorisation is withdrawn — nothing is cut off without warning.

Do you sell address space outright?

No. IPv4 Hub is a leasing marketplace. Leasing avoids the registry transfer process, the justification paperwork and the capital cost of a purchase, and it is reversible if your requirement changes.
